Denman's part-owner Harry Findlay says he has "full confidence" in the reigning Cheltenham Gold Cup champion ahead of his title defence.

A lacklustre first run of the season at Kempton after treatment for a fibrillating heart did not hold much promise, but the giant gelding is reported to be redeeming himself in his work at Paul Nicholls' stable.

"I'd love to see him win, but it's well documented that he's had the heart problem," Findlay told Radio Five Live.

"His comeback race at Kempton wasn't that great but he schooled fantastically last week - he seems in great nick.

"He's a very strong, self-purposed horse.

"Denman's the boss and I've got full confidence in him looking after himself and doing his best on the day."
